Leaf-sheath oral hairs lacking. Leaf-sheath auricles falcate. Ligule an eciliate membrane; 0.3-1 mm long; truncate. Leaf-blades flat, or involute; 8-35 cm long; 2-6 mm wide; stiff. Leaf-blade surface ribbed; smooth, or scaberulous; glabrous. Leaf-blade margins scaberulous. Leaf-blade apex acuminate; pungent; hardened.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; erect; bilateral; 4-20 cm long. Rhachis flattened; scabrous on margins. Spikelet packing broadside to rhachis; 0.5-1 their length apart; regular; 2 -rowed. Spikelets appressed; solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 3-10 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 10-20 mm long; falling entire, or breaking up at maturity; disarticulating below each fertile floret. Spikelet callus glabrous; base truncate. Rhachilla internodes obscured by lemmas.
    Fertile
    Spikelets comprising 3-10 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 10-20 mm long; falling entire, or breaking up at maturity; disarticulating below each fertile floret. Spikelet callus glabrous; base truncate. Rhachilla internodes obscured by lemmas.
    Glume
    Glumes persistent; similar; subequal in width; shorter than spikelet. Lower glume lanceolate; 8-10 mm long; 1 length of upper glume; coriaceous; 1-keeled; 5-7 -veined. Lower glume primary vein scabrous. Lower glume lateral veins ribbed. Lower glume apex acute. Upper glume lanceolate; 8-10 mm long; 0.9-1.1 length of adjacent fertile lemma; coriaceous; 1-keeled; 5-7 -veined. Upper glume primary vein scabrous. Upper glume lateral veins ribbed. Upper glume apex acute.
    Florets
    Fertile lemma oblong; 7-11 mm long; coriaceous; keeled; keeled above; 5 -veined. Lemma apex obtuse, or acute. Palea lanceolate; 1 length of lemma; 2 -veined. Palea keels scabrous. Palea apex truncate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; elliptic; membranous. Anthers 3; 5-7 mm long; dehiscent by a longitudinal slit. Stigmas 2; protandrous; laterally exserted. Ovary pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp; fusiform; isodiametric; estipitate; without sulcus; smooth; apex unappendaged. Embryo 0.2 length of caryopsis. Hilum linear; 0.9 length of caryopsis. Endosperm farinose.
